Description

Technical Field

[0001] The present application relates to the technical field of exhaust systems, and in particular to an exhaust system for indoor renovation and decoration of commercial buildings. Background Art

[0002] At present, with the continuous improvement of my country's national economic level, the construction industry is also developing steadily. Compared with the development of the construction industry in previous years, current developers have set their sights further. They no longer pursue the volume ratio and how to reduce the development cost as much as possible, but consider people-oriented and develop residential and commercial buildings with high comfort and high construction quality. In large shopping malls, large rental areas are usually divided into many independent small units and rented to different tenants. The decoration construction of local areas of shopping malls due to changes in tenants or tenant renovations is becoming more and more common. Due to the lack of effective treatment measures, local small-scale construction often greatly reduces the indoor air quality of the surrounding areas, and even affects the health of people who are in this environment for a long time. Among them, a common problem is that the exhaust vents of indoor decoration are open all year round, which not only transmits noise from the exhaust vents, but also enters dust, flying insects and garbage from the exhaust vents, which is difficult to clean and will cause pollution to the indoor air environment. For the problems in related technologies, no effective solutions have been proposed yet. Utility Model Content

[0003] In order to reduce the noise impact at the exhaust outlet of an indoor exhaust system, the present application provides an indoor renovation and decoration exhaust system for a commercial building.

[0004] The present application provides a commercial building indoor renovation and decoration exhaust system adopts the following technical solutions:

[0005] A commercial building interior renovation and decoration exhaust system comprises an exhaust fan and a box body, wherein the box body is fixed at the outlet of the exhaust system, and ventilation surfaces on both sides of the box body are missing, the exhaust fan is fixed inside the box body, and also comprises a sound insulation board, a plurality of sound insulation boards are provided, and the plurality of sound insulation boards are arranged at intervals along the length direction of one side of the box body close to the exhaust outlet, the sound insulation boards are all rotatably connected to the box body, and the rotation axis direction of the sound insulation board is perpendicular to the exhaust outlet direction of the exhaust fan, and a worm gear for driving the plurality of sound insulation boards to rotate is provided at the bottom of the box body.

[0006] By adopting the above technical scheme, a box is fixed at the outlet of the indoor exhaust system, an exhaust fan is fixed inside the box, and the sides of the box close to the wall and away from the wall are missing, which can ensure the normal operation of the exhaust system. However, because the entrance and exit of the exhaust system are open all year round, it is very easy to transmit noise and it is also very easy for dust, flying insects and other garbage to enter. A rotatable sound insulation board is set on the side of the box away from the wall. Multiple sound insulation boards can not only absorb the noise of the exhaust system when exhausting, but also close the exhaust port of the box when not exhausting, which can not only reduce the transmission of noise, but also prevent dust, flying insects, etc. from entering the box, thereby ensuring the cleanliness of the indoor exhaust system environment.

[0007] Optionally, the worm gear includes a worm wheel and a worm, and a worm wheel is fixed to the bottom of the sound insulation board through the box body, the worm is rotatably connected relative to the box body, and the rotation axis direction of the worm is perpendicular to the exhaust outlet direction of the exhaust fan, and the worm is meshed with the worm wheel.

[0008] By adopting the above technical solution, when the sound insulation board is opened, the worm is rotated, the worm is meshed with the worm wheel, the worm drives the worm wheel to rotate, and the rotation of the worm wheel drives the sound insulation board to rotate, so that the sound insulation board can be opened. When the sound insulation board needs to be closed, it is only necessary to rotate the worm in the opposite direction.

[0009] Optionally, a rotating rod is provided on the box body, a first conical tooth is coaxially fixed on the rotating rod, a second conical tooth is coaxially fixed on the end of the worm, and the first conical tooth and the second conical tooth are meshed.

[0010] By adopting the above technical solution and utilizing the meshing reversing effect of the two conical teeth, the rotation direction of the driving worm can be changed, and can be adjusted to a direction that is more convenient to use and more beautiful.

[0011] Optionally, a driving assembly is provided on the box body, and the driving assembly includes a driving rod, a connecting rod and a hinge. There are multiple hinges, and each sound insulation board is fixed with a hinge. Each hinge is hinged to the connecting rod respectively, and the driving rod is rotatably connected to the connecting rod at a non-center position, and the direction of the driving rod's rotation axis is parallel to the direction of the sound insulation board's rotation axis.

[0012] By adopting the above technical solution, since the worm gear structure is driven to rotate at the bottom of the sound insulation board, only unilateral driving is not conducive to maintaining the stability of the sound insulation board. A driving component is also added to the top position of the sound insulation board. Only the driving rod needs to be moved. The driving rod will drive the sound insulation board to rotate under the hinged action of the hinge, and multiple sound insulation boards rotate synchronously.

[0013] Optionally, a hand wheel is rotatably connected to the box body, the rotation axis direction of the hand wheel is perpendicular to the exhaust direction of the exhaust fan, and the hand wheel is hinged to the driving rod.

[0014] By adopting the above technical solution, in general, the indoor exhaust vents are located at a relatively high position, so the opening and closing of the sound insulation board is mainly driven by a motor. However, in order to debug at the beginning of installation and temporarily activate the motor when it fails, a hand wheel is installed on the box. By turning the hand wheel, the hand wheel drives the drive rod to move, and the drive rod drives the connecting rod to move, so that the sound insulation board can open and close.

[0015] Optionally, a recycling box is detachably connected to the bottom of the box, the recycling box is missing near the top surface of the box, a plurality of open holes are provided at a position near the recycling box at the bottom of the box, the plurality of open holes are arranged at intervals along the length direction of the recycling box, a scraper is slidably connected to the inside of the box, and the sliding direction of the scraper is in a direction close to or away from the recycling box.

[0016] By adopting the above technical solution, during the use of the exhaust fan, dust, flying insects and other garbage will enter the exhaust channel and the box at any time. After using it for a period of time, the scraper in the box is slid to scrape the remaining garbage inside the box to the place where the open hole is opened, and then it falls into the recycling box through the open hole. In this way, the inside of the box can be kept clean and tidy by replacing or cleaning the recycling box.

[0017] Optionally, grooves are provided on the sides of adjacent sound insulation boards that are close to each other, and the grooves on the sides of adjacent sound insulation boards fit together during sealing.

[0018] By adopting the above technical solution, the adjacent sound insulation panels can increase the sealing performance and the sound insulation effect through the matching grooves when sealing.

[0019] Optionally, sound insulation cotton is fixed on the sound insulation board.

[0020] By adopting the above technical solution, a layer of sound insulation cotton is wrapped on the sound insulation board, so that the sound insulation board can be sealed when the exhaust system is not working, thereby increasing the sound insulation effect.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. The worm gear can make multiple sound insulation panels open and close at the same time, and automatically lock after opening and closing a certain angle, so that the sound insulation panels can be opened when the exhaust system is working and closed when it is not working, which is conducive to keeping the exhaust passage clean and tidy and increasing the sound insulation effect;

[0023] 2. Push the scraper inside the box. The scraper can collect the remaining garbage inside the box through the open hole into the recycling box, which is helpful to keep the inside of the box clean. BRIEF DESCRIPTION OF THE DRAWINGS
